Description

Technical Field

[0001] The invention belongs to the technical field of wire clamps, and in particular relates to an easily locked distribution network wire clamp. Background Art

[0002] Distribution network clamps are devices used to connect and fix wires in power distribution systems. They can help ensure the stability and safety of power lines in various environments. Parallel wire clamps are a type of distribution network accessory used to connect multiple power conductors together. They are often used in the parallel connection of wires in distribution lines. Their main function is to connect two or more power conductors through a clamp and maintain smooth current transmission.

[0003] During the use of existing parallel groove wire clamps, special tools are usually required to screw the bolts so that the clamp block can press and fix the cables. It is inconvenient to operate at high altitudes and there is a risk of bolts falling. In addition, the position of the groove for placing the cables is relatively fixed, which is not convenient to adjust according to different incoming line directions, and the use effect is not good. For this reason, we propose an easy-to-lock distribution network wire clamp. Summary of the invention

[0004] The purpose of the present invention is to provide an easily locked distribution network wire clamp to solve the problem in the above background technology that the existing parallel groove wire clamps for fixing cables require special tools to tighten the bolts, which is inconvenient to operate at high altitudes and is not convenient to adjust the groove position according to different incoming line directions.

[0005] To achieve the above object, the present invention provides the following technical solution: an easily lockable distribution network clamp, comprising:

[0006] A first wire clamp body and a second wire clamp body arranged side by side with the first wire clamp body, wherein the first wire clamp body is provided with a wiring groove for placing the cable, and a copper-plated layer is fixed inside the wiring groove;

[0007] A first connecting block, fixed to the edge of the upper surface of the first wire clamp body;

[0008] A limit block is rotatably mounted on both ends of the first connecting block, and one end of the limit block has a hook plate, and a side wall of the hook plate is provided with a slot;

[0009] A second connecting block is fixed to the edge of the upper surface of the second clamp body, and a rotation adjustment component electrically connected to the copper plating layer is provided between the second connecting block and the first connecting block;

[0010] The clamping block assembly is arranged inside the first wire clamp body. When the limiting block presses the cable inside the groove, the clamping block assembly cooperates with the clamping groove to fix the limiting block.

[0011] Preferably, the clamping block assembly includes a clamping block, a clamping spring and a pull rod. The clamping block is slidably installed on the inner edge of the first wire clamp body. One end face of the clamping block is provided with a clamping spring. The pull rod is fixed to one end of the clamping block, and one end of the pull rod penetrates through the first wire clamp body and extends to the outside of the first wire clamp body.

[0012] Preferably, the cross-section of the clamping block is wedge-shaped.

[0013] Preferably, four limiting blocks are provided, and every two of the limiting blocks are symmetrically arranged at both ends of the first connecting block or the second connecting block respectively.

[0014] Preferably, the rotation adjustment assembly includes a rotating block, a pressing spring and a friction block. A rotating block is fixed to one side wall of the second connecting block. A rotating groove is correspondingly formed in one side wall of the first connecting block opposite to the rotating block. A friction block is fixed to one end inside the rotating groove. A pressing spring that presses the rotating block against the friction block is sleeved outside the rotating block.

[0015] Preferably, the rotation adjustment assembly further includes a conductive sleeve, a conductive pin and a support spring. The conductive sleeve is slidably installed on one side wall of the first connecting block, and a conductive pin is slidably connected inside the conductive sleeve. One end of the conductive pin is fixed to the copper plating layer, and the other end of the conductive pin is provided with a support spring that cooperates with the conductive sleeve.

[0016] Preferably, the cross-section of the conductive pin is "T"-shaped, and a plurality of conductive pins are evenly distributed along the circumference of the conductive sleeve.

[0019] Preferably, the hook plate is arc-shaped, and a plurality of card slots are evenly distributed along one side wall of the hook plate.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] (1) By providing the first connecting block, the limiting block, the second connecting block, the hook plate, the card slot and the clamping block assembly, it is avoided that when fixing the cable to the inside of the parallel groove clamp, it is necessary to tighten a plurality of bolts and special tools are required, which is rather laborious for high-altitude operation. This device does not require special tools and can quickly press and fix the cable to the inside of the wiring groove, completing the quick locking of the cable. The operation is simple, improving the convenience effect of high-altitude installation and increasing the practicability of the device.

[0022] (2) By providing a rotating block, a clamping spring, a friction block, a conductive sleeve, a conductive foot and a supporting spring, the relative positions of the two pairs of cable placement grooves of the parallel groove wire clamp are prevented from being fixed. When the cables come from different directions, it is inconvenient to adjust the positions of the placement grooves to adapt to the incoming direction of the cables. The device can adjust the positions of the first wire clamp body and the second wire clamp body according to the incoming direction of the cables, thereby adjusting the direction of the wiring groove to adapt to the cables. The operation is simple, the application range of the device is expanded, and it is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] A first connecting block 3, fixed to the edge of the upper surface of the first wire clamp body 1;

[0036] The limit block 4 is rotatably mounted on both ends of the first connection block 3, and one end of the limit block 4 has a hook plate 8, which is convenient for quickly adjusting the position of the limit block 4, so that the cable is pressed and fixed to the inner side of the wiring groove through the limit block 4, and a card slot 9 is opened on one side wall of the hook plate 8;

[0037] The second connection block 5 is fixed to the upper edge of the second wire clamp body 2, and a rotation adjustment component 7 electrically connected to the copper plating layer 6 is provided between the second connection block 5 and the first connection block 3, so as to facilitate the transmission of the power of the cable inside the wiring groove on the first wire clamp body 1 to the cable inside the wiring groove on the second wire clamp body 2;

[0038] The clamping block assembly is arranged on the inner side of the first wire clamp body 1. When the limit block 4 presses the cable inside the groove, the clamping block assembly cooperates with the clamping groove 9 to fix the limit block 4, so as to lock the position of the limit block 4 after the limit block 4 presses the cable.

[0039] Preferably, the card block assembly includes a card block 10, a locking spring 12 and a pull rod 11, the card block 10 is slidably installed on the inner edge of the first wire clamp body 1, and one end face of the card block 10 has a locking spring 12, the pull rod 11 is fixed to one end of the card block 10, and one end of the pull rod 11 passes through the first wire clamp body 1 and extends to the outside of the first wire clamp body 1, so as to facilitate the cooperation between the card block 10 and the card slot 9 to complete the locking of the position of the limit block 4.

[0040] Preferably, the cross section of the card block 10 is wedge-shaped, so that when the hook plate 8 is pressed into the inner side of the first wire clamp body 1, the hook plate 8 can be moved down without pulling the pull rod 11. When the hook plate 8 is unlocked, the card block 10 needs to be withdrawn from the inner side of the card slot 9 by pulling the pull rod 11.

[0041] Preferably, four limit blocks 4 are provided, and every two limit blocks 4 are symmetrically arranged at two ends of the first connecting block 3 or the second connecting block 5 .

[0042] Preferably, the rotation adjustment assembly 7 includes a rotation block 701, a compression spring 702, and a friction block 703. A rotation block 701 is fixed to one side wall of the second connection block 5. A rotation groove is correspondingly formed in one side wall of the first connection block 3 opposite to the rotation block 701, and a friction block 703 is fixed to one end inside the rotation groove. A compression spring 702 that presses the rotation block 701 against the friction block 703 is sleeved outside the rotation block 701, which facilitates the relative rotation between the first wire clamp body 1 and the second wire clamp body 2, so as to adjust the orientation of the wiring groove to cooperate with the cables entering from different directions.

[0043] Preferably, the rotation adjustment assembly 7 further includes a conductive sleeve 704, a conductive pin 705, and a support spring 706. The conductive sleeve 704 is slidably installed on one side wall of the first connection block 3, and a conductive pin 705 is slidably connected inside the conductive sleeve 704. One end of the conductive pin 705 is fixed to the copper plating layer 6, and a support spring 706 that cooperates with the conductive sleeve 704 is provided at the other end of the conductive pin 705, which facilitates the real-time electrical connection between the wiring groove on the first wire clamp body 1 and the wiring groove on the second wire clamp body 2 during rotation adjustment.

[0044] Preferably, the cross-section of the conductive pin 705 is "T"-shaped, and a plurality of conductive pins 705 are evenly distributed along the circumferential direction of the conductive sleeve 704, which facilitates a better conductive effect.

[0045] Preferably, there are two conductive sleeves 704. The other conductive sleeve 704 is arranged on one side wall of the second connection block 5. The cross-section of the support spring 706 is "匚"-shaped, which facilitates the real-time contact between the two conductive sleeves 704 and maintains a good electrical connection.

[0046] Preferably, a twisted pair wire 131 is fixed to the lower surface of the first wire clamp body 1, and a metal rod 132 is fixed to the lower end of the twisted pair wire 131, which facilitates converting the vibration force in the air into the kinetic energy of the metal rod 132, thereby weakening the vibration force to reduce the impact on the device.

[0047] Preferably, the hook plate 8 is arc-shaped, and a plurality of card slots 9 are evenly distributed along one side wall of the hook plate 8.

[0048] The working principle and use process of the present invention are as follows: when in use, according to the positions of the two cables, the second wire clamp body 2 is first pulled toward the side away from the first wire clamp body 1, so that the second wire clamp body 2 drives the rotating block 701 to separate from the friction block 703 through the second connecting block 5. At this time, the clamping spring 702 is squeezed and shortened, and the rotating block 701 rotates inside the rotating groove to adjust the wiring groove on the second wire clamp body 2 to correspond to one of the cables, and the wiring groove on the first wire clamp body 1 to correspond to the other cable. The second wire clamp body 2 is released, and the rotating block 701 and the friction block 703 are contacted and rubbed under the elastic push of the clamping spring 702, and the rotation of the rotating block 701 is limited by a large friction force. Then, the limit block 4 is rotated to compress the cable inside the wiring groove, so that the hook plate 8 at one end of the limit block 4 moves toward the clamping block 10 until the clamping groove 9 is engaged with the clamping block 10, so that the position of the limit block 4 can be quickly locked to complete the fixation of the cable.
